1998 Lexus LS400 towing

GAUGES, METERS AND SERVICE REMINDER INDICATORS
35 Idling for a long period with the air conditioning on in
stopandgo traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling system as
this may cause the engine to overheat. The thermostat is
designed to control the flow of coolant to keep the
temperature of the engine within the specified operating
range.
Do not continue driving with an overheated engine. See ”If
your vehicle overheats” on page 196.
TACHOMETER
13L0031
The tachometer indicates engine speed in thousands of rpm
(revolutions per minute). Use it while driving to prevent engine
overrevving.
Driving with the engine running too fast causes excessive engine
wear and poor fuel economy. Remember, in most cases the slower
the engine speed, the greater the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may
cause severe engine damage.

(a) Brake System Warning Light
This light has the following two functions:
Parking brake reminder
If this light is on, make sure the parking brake is fully released. The
light should go off.
Low brake fluid level warning
If this light comes on and stays on while you are driving, slow down
and pull off the road. Then stop the vehicle carefully. Remember
that stopping distance and pedal effort may be increased. There may
be a problem somewhere in the brake system. Check the fluid level
of the seethrough reservoir.
To make sure the parking brake has not caused the warning light to
come on, check to see that the parking brake is fully released.
If the brake fluid level is low ...
At a safe place, test your brakes by starting and stopping.
If you judge that the brakes still work adequately, drive cautiously
to your nearest dealer or shop for repairs.
If the brakes are not working, have the vehicle towed in for
repairs. (For towing information, see page 205.)
CAUTION
It is dangerous to continue driving normally when the brake
fluid level is low.

CAUTION
Make sure the floor mat is properly placed on the floor carpet.
If the floor mat slips and interferes with the movement of the
pedals during driving, it may cause an accident.
LUGGAGE STOWAGE
PRECAUTIONS
When stowing luggage or cargo in the vehicle, observe the
following:
Put luggage or cargo in the trunk when at all possible. Be sure all
items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far
forward as possible helps maintain vehicle balance.
For better fuel economy, do not carry unnecessary weight.
CAUTION
Do not place anything on the filler panel behind the rear
seatback. Such items may be thrown about and possibly
injure people in the vehicle during sudden braking or an
accident.
Do not drive with objects left on top of the instrument
panel. They may interfere with the driver’s field of view.
Or they may move during sharp vehicle acceleration or
turning, and impair the driver’s control of the vehicle. In
an accident they may injure the vehicle occupants.

STARTING AND DRIVING
163 5. Release the parking brake and brake pedal. Depress the
accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in the first gear and
automatically shift up to the most suitable gear. On inclines, declines
or winding roads, etc., the vehicle shifts up and down automatically
according to the running conditions to obtain the suitable driving
power and engine braking.
In ”4” position, the automatic transmission system will select the
most suitable gear for the running conditions such as hill climbing,
hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides more
acceleration by automatically downshifting the transmission to the
next lower gear or beyond, depending on the vehicle speed.
If engine braking is needed, such as in descending a long hill, see ”(b)
Using engine braking”.
(b) Using engine braking
31L010-3
To use the braking power of the engine, downshift the transmission
in the way described below:
1
Shift into the ”4” position. The transmission will downshift to
the fourth gear and engine braking will be obtained.
When the cruise control is being used, even if you downshift
from ”D” to ”4”, engine braking will not be applied because the
cruise control is not cancelled. If you need to decrease the
vehicle speed, see page 170.
2
Shift into the ”3” position. The transmission will downshift to
the third gear when the vehicle speed is or becomes lower than
154 km/h (96 mph) and more powerful engine braking will be
obtained.

STARTING AND DRIVING
164
3
Shift into the ”2” position. The transmission will downshift to
the second gear when the vehicle speed is or becomes lower
than 104 km/h (65 mph) and more powerful engine braking
than that of ”3” position will be obtained.
4
Shift into the ”L” position. The transmission will downshift to
the first gear when the vehicle speed is or becomes lower than
18 km/h (11 mph) and maximum engine braking will be
applied.
CAUTION
Be careful when downshifting on a slippery surface. The
abrupt change in engine speed could cause the vehicle to spin
or skid.
(c) Using the ”3”, ”2” and ”L” positions
The ”3”, ”2” and ”L” positions are used for strong engine braking as
described previously.
With the selector lever in ”3”, ”2” or ”L”, you can start the vehicle
in motion as with the lever in ”D”.
With the selector lever in ”3” or ”2”, the vehicle will start in the first
gear and automatically shift to the third or second gear.
With the selector lever in ”L”, the transmission is engaged in the first
gear.
NOTICE
Be careful not to overrev the engine. Watch the tachometer
to keep engine rpm from going into the red zone. The
approximate maximum allowable speed for each position is
given below for your reference:
”3” 160 km/h (99 mph). . . .
”2” 104 km/h (65 mph). . . .
”L” 68 km/h (42 mph). . . .
Do not continue hill climbing or hard towing for a long time
in the ”3”, ”2” or ”L” position. This may cause severe
automatic transmission damage from overheating. To
prevent such damage, ”4” position should be used in hill
climbing or hard towing.

STARTING AND DRIVING
166
(f) Good driving practice
If the transmission repeatedly upshifts and downshifts between
the fourth and overdrive gears when climbing a gentle slope, shift
the selector lever to the ”4” position. Be sure to shift the selector
lever to the ”D” position after climbing the slope.
When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive. The selector lever must be in the ”4” position.
CAUTION
Always keep your foot on the brake pedal while stopped with
the engine running. This prevents the vehicle from creeping.
NOTICE
Do not hold the vehicle on an upgrade with the accelerator
pedal. This can cause the transmission to overheat. Always use
the brake pedal or parking brake.
(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in snow, mud, sand, etc., then
you may attempt to rock the vehicle free by moving it forward
and backward. Do not attempt this procedure if people or
objects are anywhere near the vehicle. During the rocking
operation the vehicle may suddenly move forward or back as
it becomes unstuck, causing injury or damage to nearby
people or objects.
NOTICE
If you rock your vehicle, observe the following precautions to
prevent damage to the transmission and other parts.
Do not depress the accelerator pedal while shifting the
selector lever or before the transmission is completely shifted
to forward or reverse gear.
Do not race the engine and avoid spinning the wheels.
If your vehicle remains stuck after rocking the vehicle several
times, consider other ways such as towing.

DRIVING TIPS
183 Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto parts
stores. Follow the manufacturer’s directions for how much to mix
with water.
NOTICE
Do not use engine antifreeze or any other substitute because it
may damage your vehicle’s paint.
Do not use your parking brake when there is a possibility it could
freeze.
When parking, put the transmission into ”P” and block the front
wheels. Do not use the parking brake, or snow or water accumulated
in and around the parking brake mechanism may freeze the parking
brake, making it hard to release.
Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering difficult.
During bad winter driving, stop and check under the fenders
occasionally.
Depending on where you are driving, we recommend you carry
some emergency equipment.
Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel, jumper
cables, etc.
TRAILER TOWING
Your vehicle is designed primarily as a passengercarrying vehicle.
Towing a trailer will have an adverse effect on handling,
performance, braking, durability and driving economy (fuel
consumption, etc.). Your safety and satisfaction depend on the
proper use of correct equipment and cautious driving habits. For
your safety and the safety of others, you must not overload your
vehicle or trailer. Lexus warranties do not apply to damage or
malfunction caused by towing a trailer for commercial purposes.
Ask your local Lexus dealer for further details before towing.
NOTICE
When towing a trailer, be sure to consult your Lexus dealer for
further information on additional requirements.
Weight limits
Before towing, make sure the total trailer weight, gross vehicle
weight, gross axle weight and trailer tongue load are all within
the limits.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.
